Description

A kind of wireless alarm system for preventing secondary accidents of freeway tunnel group
Technical field
The present invention relates to a kind of highway warning system, specifically be meant a kind of wireless alarm system for preventing secondary accidents of freeway tunnel group based on the Zigbee technology.
Background technology
The tunnel second accident is meant that vehicle has an accident or during scram at tunnel internal, and follow-up vehicle can not in time be known and still sails at a high speed under the situation in the hole and accidents such as knocking into the back of causing, collision.In order to reduce the generation of tunnel second accident, in time that accident and fault-signal transmission and indication is most important to the driver that each enters the tunnel.But at present, lack and a kind ofly effectively trouble-signal is in time passed to the driver that each enters the tunnel, its traditional way generally is exactly after in the tunnel car accident or fault taking place, the vehicle that meets accident is opened trouble light, dial the phone of seeking help, wait for that the traffic police handles, but because light is dim relatively in the tunnel, in the process of waiting for the traffic police, when follow-up vehicle enters the tunnel, especially when the vehicle of running on expressway enters the tunnel, often can not in time see the trouble light signal of fault vehicle, make the driver in time not carry out to slow down work such as dodge to cause the generation of second accident, bring heavy losses to people's lives and properties.
Summary of the invention
The objective of the invention is to reduce the wireless alarm system for preventing secondary accidents of freeway tunnel group that the tunnel second accident takes place and provide a kind of in order to overcome the shortcoming and defect that prior art exists.
For achieving the above object, technical scheme of the present invention is, comprise the warning base station, signal repeater, the onsite alarming assembly, remote controllers and Surveillance center, described warning base station distribution is arranged at tunnel internal and is used for when starting alerting signal in the tunnel during generation accident, described onsite alarming assembly is arranged at the tunnel portal place, the alerting signal of described warning base station is transmitted between each warning base station in the tunnel by wireless network, and accident alarming signal that should the warning base station finally reaches remote controllers, and by remote controllers driving onsite alarming assembly, remind follow-up vehicle deceleration or be prohibited from entering the tunnel by the mode of acousto-optic picture and text, described remote controllers intercom with Surveillance center mutually by the GSM/GPRS network, and this Surveillance center can carry out remote monitoring to field apparatus and alarm condition by remote controllers.By this setting, in case have an accident or vehicle trouble stop, as long as any one warning base station triggers is arranged reports to the police, its alerting signal is promptly passed to other warning base station by wireless network, finally reach remote controllers, drive warning horn and variable information board by remote controllers, remind follow-up vehicle to enter tunnel group no longer at a high speed, second accident such as to avoid collision, knock into the back by the mode of acousto-optic picture and text.
Further being provided with is the porch that described onsite alarming assembly is arranged at the tunnel group that is made of a plurality of tunnels, and is provided with signal repeater between the adjacent tunnel, and a plurality of tunnels are connected to form a tunnel group warning system.By this setting, highway section in the many tunnels of highway, a plurality of adjacent tunnels can be connected to form a tunnel group warning system by signal repeater, not only reduce the equipment installation cost, and second accident such as can prevent that effectively whole tunnel group from colliding, knocking into the back.
Further being provided with is that described onsite alarming assembly includes variable warning intelligence plate, warning horn and lane signal lamp.By this setting, variable warning intelligence plate, warning horn and lane signal lamp are with every vehicle drivers that enters the tunnel of acousto-optic graphics context mode caution, good warning effect.
Further being provided with is that described warning base station and the signal repeater between the tunnel that is arranged in the tunnel formed the Zigbee wireless network, and described remote controllers are Zigbee network center node device.Zigbee is the synonym of IEEE 802.15.4 agreement, have closely, low complex degree, low-power consumption, low data rate, characteristics cheaply, meet very much the in-plant network application of high capacity, so the present invention adopts the Zigbee wireless network to have cost advantage preferably.
When the accident alarming signal that further setting is the warning base station is triggered, the direction transmission of the only past tunnel portal of its alerting signal, the follow-up warning base station that receives the accident alarming signal is rotated setting caution panel thereon simultaneously, red blue caution LED lamp on this caution panel begins flicker, reminds the driver who has entered tunnel group to slow down and goes slowly.By this setting, to transmit eye-catching information warning for more intuitively the driver who enters tunnel group, further improve the ability that the present invention prevents the tunnel second accident, and the direction transmission of the only past tunnel portal of alerting signal, can reduce the transmission quantity of alerting signal, improve the validity of signal transmission, warn, therefore also conserver power source cost effectively because there is no need to launch its warning base station along the warning base station vehicle approach axis and that be positioned at the back, warning base station of triggering alerting signal.
Further being provided with is that described warning base station is installed on inwall both sides, tunnel, and setting height(from bottom) is apart from ground 1.8-1.9 rice.By this setting, 1.8-1.9 the caution panel on the high warning of the rice base station can arrive for better the driver observation that enters the tunnel, can there be visual dead angle, and uses hand deactivation warning base station triggers accident alarming signal can for easily the driver who fault or accident vehicle occur.
Further being provided with is 15~30 meters at interval of adjacent two warning base stations.This setting makes the caution effect of warning base station and cost obtain comprehensive consideration, has promptly saved cost, has again and warns the warning effect easily.
Further being provided with is that described warning base station comprises circuit part and dynamo-electric drive part, described circuit part includes Zigbee communication module, governor circuit module, described Zigbee communication module, governor circuit module adopt the power supply of high capacity disposable lithium-battery, and described dynamo-electric drive part adopts tunnel internal cable and the power supply of battery AC-battery power source.
The present invention is based on Zigbee wireless communication network technology, arrange outside a series of radio alarmings base station and the tunnel that by in the tunnel, arranging variable warning intelligence plate, warning horn, lane signal lamp constitute the onsite alarming assembly.When accident takes place, the alarm button alerting signal of base station of only need pushing for emergency promptly is triggered and passes to other warning base station of tunnel portal direction successively, on the advices plate outside the tunnel, advices plate no longer enters the tunnel with the form caution exterior vehicle of various acousto-optic picture and text, prevents the generation of second accident.Except that onsite alarming equipment, native system is furnished with remote monitoring software at tunnel operation control center, can carry out real-time dynamic monitoring to field condition, reaches synchronous commander's purpose.By test, the present invention can effectively prevent the generation of second accident in the tunnel, reach the purpose that the driver saves oneself, rescues mutually, reduce the loss of people's lives and properties, accelerate the reaction velocity of highway traffic police simultaneously to emergency case in the tunnel, promote the level of scientific management of highway unit of operation, thereby ensure the unobstructed efficient operation of highway to greatest extent.
